The health condition of incarcerated RJD supremo Lalu Prasad Yadav, who is undergoing treatment at the Rajendra Institute of Medical Sciences (RIMS), is serious but stable, a hospital official said.

The formidable political leader and former union minister was sentenced by a special CBI court to five years` prison term and slapped with a fine of Rs 60 lakh during the day in connection with the embezzlement of Rs 139 crore from Doranda treasury in the fodder scam. The court had convicted Kumar on February 15 and pronounced the quantum of the sentence after virtually hearing the arguments.
